Introduction to 365 rad

Lecturer name: DR ALBADR

Chairman of radiology department

Lecture Date: 2011


Lecture Objectives..

1- to learned different type of radiology modalities.

2- to have the principle of the indication and contra- indication for different radiology investigation .

3- Usage of different type of contrast.


Look to the shadow (image)


Which eye is affected


The disease in the globe is (retinoblastoma)


The aim of the physician to reach the diagnosis before surgery


The body is complex simulating a map


  • WHAT is X RAY ?

  • ELECTROMAGNATIC RADIATION CAUSING IONIZATION IN THE BODY.

  • X RAY IS COMING FROM ??? WHERE ?

  • You need :

  • 1- machine .

  • 2-Patient .

  • 3-detector .


German physicist Wilhelm Röntgen discoverer of X-rays in 1895

1-Air is translucent

2- Is the air inside the bowel or outside the bowel


Pneumopertonuim


  • Pneumothorax :

  • A pneumothorax is an abnormal collection of air or gas in the pleural space that separates the lung from the chest wall

  • Pnuemoperitoneum :

  • Pneumoperitoneum is the presence of air or gas in the abdominal (peritoneal) cavity. It is often seen on X-ray, but small amounts are often missed, and CT is needed...


Contrast study

  • Oral contrast:

  • Baruim swallow :A barium swallow (or esophagography) is a medical imaging procedure used to examine the upper GI (gastrointestinal) tract

  • Baruim meal :A barium meal, also known as an upper gastrointestinal series is a procedure in which radiographs of the esophagus, stomach and duodenum

  • Baruim enema :A barium enema, or lower gastrointestinal (GI) examination.

  • I V Contrast :

  • Angiogram

  • Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels .

Contrast is radio-opaque


What is the organ examined by this test ?

  • 1-Myelogram

  • 2-sialogram

  • 3-mamogram

  • 4-sinogram

  • 5- MRCP

  • Magnetic resonance cholangiopancreatography

  • 6-ERCP Endoscopic Retrograde Cholangio-Pancreatography

  • Ultrasound

    An ultrasound machine creates images that allow various organs in the body to be examined.

    The machine sends out high-frequency sound waves, which reflect off body structures.

    A computer receives these reflected waves and uses them to create a picture. Unlike with an x-ray or CT scan, there is no ionizing radiation exposure with this test.


  • Ultrasound

  • Aim

  • Tech

  • Advantage vs disadvantage

    Organ limitation

    Uses


US MACHINE


LIVER AND KIDENY


Us appearance

  • Hyper –echoic:

    Means More bright

  • Hypo-echoic :

    Means Less bright

  • US cannot penetrate

  • Bone and air

  • (skull –lung )

  • Us is operator

  • Dependant

  • Can we do it for

  • Pregnant patient ?


GALL STONE


CT MACHINE


  • -Xray computed tomography, also computed tomography (CT scan), computed axial tomography (CAT scan) or computer assisted tomography is a medical imaging procedure that uses computer-processed X-rays to produce tomographic images or 'slices' of specific areas of the body.

  • These cross-sectional images are used for diagnostic and therapeutic purposes in various medical disciplines.


REMEMBER

  • THERE IS A LARGE AMOUNT OF RADITION

    IN CT EXAMINATION

  • DURING THE STUDY :

  • iv CONTRAST IS USEDE

    WITH PRECAUTION

  • ORAL CONTRAST

    IS SAFE

RADITION RISK-pregnancy ?

MR MACHINE


MRI

  • MRI can create more detailed images of the human body than are possible with X-rays.

  • is a Medical imaging used in radiology to visualize internal structures of the body in detail.


  • An MRI scanner is a device in which the patient lies within a large, powerful magnet where the magnetic field is used to align the magnetization of some atomic nuclei in the body,

  • Radiofrequency magnetic fields are applied to systematically alter the alignment of this magnetization.This causes the nuclei to produce a rotating magnetic field detectable by the scanner—and this information is recorded to construct an image .
